It has a bug (which I don't remember seeing a fix for) that it will only process one entry from the command ring each time the doorbell is rung. If more than one command gets queued then it all got very confusing because responses to timed out commands kept being seen. (I no longer have the USB3 ethernet device needed to reproduce this.) The later part might have the same bug. David
